e of Ghio, have invented certain ul Improvements in Demount- -Gear Bearing-Caps; and we J declare the following to be a full, it cl ar, and exact description of the invenn, such as will enable others skilled in the art which it appertains to make and use the same.

This invention-relates to new and useful improvements in demountable couple-gear bearings particularly adaptable for internal gear construction and has for one oi its objects the provision of means whereby the outer ends or the drive axles of a motor vehicle or tractor are firmly supported and which will permit the easy removal of the axles from the differential housing after the V removed or detached, thereby full floating power delivering e object of this invention is the of a demountable couple-gear cf the character stated which sup- .e axles on each side of the drive pinich keeps them in true alinement internal ring gears of the wheels,

urther object of this invention isthe provision of cups adapted to receive the drive pinions and catch lubricant from the ring during their rotation, so that pinions are continuously bathed in and which permits the pinions to pcsit lubricant on the ring gears at their p Hits of mesh with said ring gears, thereincreasing the life of said pinions and gea "iv these and other objects in view as become more apparent as the description proceeds, the invention consists in certain novel features of construction, combi' nation, and arrangement of parts as will be hereinafter more fully describedand claimed.

For a complete understanding of our invention, reference is to be had to the following description and accompanying drawin which:

Figure 1 is a vertical sectional view illustrating a demountable couple-gear bearing cap associated with a wheel and constructed in accordance with our invention,

Fig. 2 is a front elevation illustrating a guard plate having formed'integrally therewith a lubricant receiving cup,

Fig. 3 is a vertical sectional view or the same, v v Fig. an elevational view looking the inner face of a cap,

a vertical sectional view of the same,

1g. 6 1s a perspective view drawn on an enlarged scale illustrating the cap.

Referring in detail to the drawings, the numeral 1 indicates a fragmentary portion of a differential housing having load and drive or power axles 2 and 3 respectively and a guard plate 4 is secured to the end of the differential housing 1 by fasteners 5 and 18 provided with openings to permit the load and power axles 2 and 3 respectively to extend therethrough. A wheel 6 forming subject matter for a co-pending apphoation is journaled on the axle 2 and has secured in the hub 7 thereof a ring gear 8. An annular flange 9 is formed on the guard plate 4 and overlies the hub 7 and is provided with packing 10 which establishes a leak-proof connection between the hub and the guard plate 4 to prevent lubricant within the hub from escaping.

A hearing 11 is mounted in the guard plate 1 and rotatably supports the power or drive axle 3 at a point where said axle passes through the guard plate. A drive pinion 12 is secured to the power or drive axle 3 and meshes with the internal gear 8 at its highest point and said drive or power axle 3 projects beyond said pinion as clearly illustrated in Fig. 1.

A cup 13 is formed integrally with the guard plate 4 about the drive or power axle opening and includes a substantially arcuate shaped wall 14; which defines top and end openings to the cup so that the drive pinion 12 located in the cup can mesh with the ring gear 8 by way of the top opening and said top opening also permits lubricant to drop into the cup from the ring gear during the rotation thereof. An arcuate shaped flange 15 is formed on the outer edge of the arcuate shaped flange 14 and defines the end opening to the cup. A cap 16 is detachably secured to the flange 15 by fasteners and is adapted to close'the end opening and end is open to receive the outer end of the drive or power axle 3; A hearing 19 is 10,-; cated in the body 17 and rotatably supports consists of a hollow body 17 which has one end closed by an end wall 18 while its other permits the drive or poweraxle to be readily withdrawn from -the differential housing and the usual difi'erential located therein as it is only necessary to remove the cap 16 after the removal of the wheel 6 and the axle 3 can then be pulled out. This construction also readily catches the lubricant brought up by the rotation of the ring gear 8 and continuously bathes the drive pinion, permltting said pinion to deposit lubricant onto the ring gear at its point of mesh with said ring gear and which is the highest point of said ring gear. Also this construction prevents the drive pinion from becoming out of alinement with the ring gear 8 thus increasing the life of the gear and pinion.

While we have shown and described the preferred embodiment of our invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described our invention, what we claim is l. A device of the character set forth comprising a plate, power and load carrying' axles extending through the plate, a wheel journaled on said load carrying axle, a gear secured to the wheel, a pinion secured to the power axle and in mesh with the gear, means supporting the power axle at one side of the pinion, a lubricant receiving cup carried by said plate and inclosing a portion of the pinion, means detachably secured to the cup for supporting the power axle at the opposite side of the pinion and capable of being removed to permit the power axle to be withdrawn without the removal of the pinion.

- 2; A device of the character set forth comprising a plate, poweriand load carrying axles extending through theeplate, a

wheel journaled on said load carrying axle,

a gear secured to the wheel, a pinion secured to the power axle and in mesh with the gear,

a bearing carried by said plate and rotatably supporting the power axle at one side ing its top and one end open, a cap removably secured to the cup and closing the end thereof, and a bearing carried by said cap and supporting the power axle at the other side of the pinion.

s. A device of the character set forth comprising a guard plate, power and load carrymg axles extending through the plate, a wheeljournaled on said'loadcarrying axle, a flange formed on the guard plate and overlyingthe hub of the wheel, an internal gear secured in the hub of the wheel, thehub of the wheel adapted to contain lubricant for the gear, a pinion'secured to the power axle and in mesh-with the gear at its highest point, a bearing carried by the guard plate and rota tably supporting the power axle at one side of said pinion, a cup formed on said plate and receiving said pinion and adapted to catch lubricant from the gear during the rotation thereon-and a removable bearing cap carried by said cup and supporting the power axle at the opposite side of said pinion. e
